BACKGROUND OF THE INVENTION

[0010] This invention relates to a novel comprehensive composition comprising the major inorganic salts, urea, organic compounds, organic ammonium salts, proteins and human immuglobins present in normal human urine formulated into unisex synthetic human urine. The use of sodium azide as a preservative solution is also disclosed.

[0011] Urine tests are an important and useful diagnostic tool because they are easily obtained and inexpensive. Urine provides important information about a number of physiological processes, including but not limited to renal disease, diabetes mellitus, hydration status, toxicology, and some liver diseases. Many people will have a routine urine examination upon admission to a hospital, and many outpatient settings do routine analyses as well.

[0012] Blood is filtered by the kidneys, producing urine to rid the body of wastes and to regulate fluid and electrolyte balance. The normal adult produces between 1.0 to 1.5 liters of urine daily. Enormous amounts of fluids pass through the kidneys every day, as about a thousand liters of blood need to pass through the kidneys to produce one liter of urine.

[0013] The nephron is the primary unit of the kidney that produces urine, and each kidney has about one million nephrons. The nephron is composed of the glomerular capsule, the proximal convoluted tubule, the loop of Henle, and the distal convoluted table, which empties into a collecting tubule. Every minute about 125 mL of blood is filtered by the glomerli in an adult male, slightly less in an adult female. The nephrons filter the blood of electrolytes, glucose, water, and small proteins, most of which is reabsorbed in the proximial tubule. Urine in the healthy person contains 96% water and 4% solutes, primarily urea and sodium chloride.

[0014] Despite the ease of urine collection, many problems in the handling of specimens occur which will provide inaccurate results. Problems can occur with the collection process, the handling of the urine specimen, or with urine testing. Most urine tests require a minimum of 10 cc of urine. Urine is collected through several methods; catherization, clean-catch, first morning, and pediatric collection.

[0015] Urine specimens must be examined within two hours of collection to avoid bacterial contamination. Bacteria that are present within the urine at collection will convert urea to ammonia, giving false alkaline readings. The alkalinity, in turn, leads to breakdown of casts and proteins. To avoid these problems, urine should be immediately refrigerated if it cannot be analyzed within a two hour period.

[0016] The disclosed invention in the application is a synthetic urine composition containing all the major analogs of normal unisex human urine.

[0017] In response for the need of a reliable source of comprehensively biologically complete standard human urine analog numerous attempts to formulate synthetic urine have been made. For example, U.S. Pat. No. 6,306,422 to Batich et al. (table 3, col. 16, line 50 et seq.), U.S. Pat. No. 5,328,954 to Sarangapani (table 1, col. 9, line 29 et seq.), U.S. Pat. No. 5,489,281 to Watanabe et al. (col. 12, example 6), U.S. Pat. No. 4,146,644 to Griffith et al. (table 1, col. 10), and U.S. Pat. No. 7,192,776. However, none of these references address a composition similar to unisex human urine with all its major constituents.

[0018] Further, all the references do not have all the desired composition of human urine and fail to include compounds which are necessary for a comprehensive control for human urine in diagnostic testing methods available to one ordinarily skilled in the art that include but are not limited to human immunoglobins, mammalian derived sources of albumin, inorganic salts, organic compounds, and organic ammonium salts.

[0019] The invention disclosed in this application comprises a composition similar to natural human unisex urine. The invention disclosed is useful for all manners of diagnostic testing of human urine where the use of a comprehensive composition is desired.

[0020] The invention disclosed in this application can be used in the following including urinalysis, and standard diagnostic testing methods comprising but not limited to, toxicology, urinanlysis, 11-deoxycortisol, 17-hydroxycorticosteriods, 17-ketosteroids, 4-pyrodoxic acid, 5-hydroxyindoleacetic acid, 5-hydroxyproline, addis count, albumin, aldosterone, amino acids, arylsulfate A, Bence Jones Protein, Benedicts test, cyclic adenosine monophosphate, delta-aminolevulinic acid (ALA), dexamethasone suppression, dinitrophenylhydrazine, D-xylose absorption, ferric chloride, glucose, hemosiderin, hydroxyproline, indicant, ketone bodies, melanin, melanocyte-stimulating hormone, mucopolysaccharides qualitiative, nitrate bacteria screen, osmolality, oxalate, phenistix, pregnanetriol, protein electrophoresis, schilling test, specific gravity, thiocyanate, toxicology screening, twenty four hour urine, urethral pressure profile, urinalysis, urine phosphate, urobilinogen, urine phospahate, urobilinogen, vitamins B, water deprivation, water loading and xanthuric acid, and drug screens.
